It seems that app_swift does not work with Asterisk 15 or 16.  I
just get errors when trying to compile:

[root@pbxoficina app_swift]# ./configure checking gcc… checking swift… checking asterisk… creating Makefile
  ********************************************************
  *  Now run ‘make’ to compile app_swift                 *
  ********************************************************
[root@pbxoficina app_swift]# make

……

    Is there a better way to use Cepstral voices for TTS on Asterisk?
